| 英文摘要 | a new pulse sequence entitled dq-drenar (double-quantum based dipolar recoupling effects nuclear alignment reduction) was recently described for the quantitative measurement of magnetic dipole-dipole interactions in homonuclear spin-1/2 systems involving multiple nuclei. as described in the present manuscript, the efficiency and performance of this sequence can be significantly improved, if the measurement is done in the constant-time mode. we describe both the theoretical analysis of this method and its experimental validation of a number of crystalline model compounds, considering both symmetry-based and back-to-back (baba) dq-coherence excitation schemes. based on the combination of theoretical analysis and experimental results we discuss the effect of experimental parameters such as the chemical shift anisotropy (csa), the spinning rate, and the radio frequency field inhomogeneity upon its performance. our results indicate that constant-time (ct-) drenar is a method of high efficiency and accuracy for compounds with multiple homonuclear spin systems with particular promise for the analysis of stronger-coupled and short t-2 spin systems.
